ΕΡ 2 146 796/ΡΤ DESCRIÇÃO "Misturador para betão e misturas similares que permite uma limpeza interna fácil e segura" 0 pedido do presente invento refere-se a um misturador para betão, pós, granulado seco e meio seco, caracterizado por uma limpeza interna fácil e segura.ΕΡ 2 146 796 / ΡΤ DESCRIPTION " Mixer for concrete and similar mixtures allowing easy and safe internal cleaning " The application of the present invention relates to a mixer for concrete, powders, dry granulated and dry media, characterized by easy and safe internal cleaning.
Tal como é sabido, os misturadores tradicionais utilizados nos mais diversos sectores, com particular referência para o sector da construção, são compostos por um grande tanque paralelepipédico com paredes cilíndricas ou em forma de ómega, nas quais um ou mais veios de rotação operam de modo horizontal para misturar as misturas carregadas no tanque.As is known, traditional mixers used in a wide variety of sectors, with particular reference to the construction sector, are composed of a large parallelepiped tank with cylindrical or omega-shaped walls in which one or more rotating shafts operate horizontal to mix the mixtures loaded in the tank.
Os referidos veios são proporcionados com pás radiais concebidas para interferir de modo eficaz com a mistura a ser misturada.Said shafts are provided with radial blades designed to effectively interfere with the blend to be blended.
Os bordos transversais do tanque são proporcionados com alojamentos utilizados para inserir os veios de mistura, com a interposição de chumaceiras adequadas e juntas de vedação.The transverse edges of the tank are provided with housings used to insert the mixing shafts, with the interposition of suitable bearings and sealing gaskets.
As unidades motoras concebidas para colocarem cada um dos veios de mistura a rodar estão montadas numa posição externa num ou em ambos os bordos transversais. A unidade motora é composta por um motor eléctrico que actua, quer directamente quer por meio de uma correia de transmissão, um motor de engrenagem que transmite o movimento rotativo ao veio de mistura com a interposição de uma série de engrenagens intermédia e de redução.The motor units designed to place each of the mixing shafts to rotate are mounted in an external position on one or both of the transverse edges. The motor unit is composed of an electric motor which acts either directly or by means of a drive belt, a gear motor which transmits the rotary motion to the mixing shaft with the interposition of a series of intermediate and reduction gears.
Em geral, o referido motor eléctrico tem uma velocidade de aproximadamente 1400 rpm, que corresponde a uma velocidade reduzida em no motor de engrenagem e uma velocidade de aproximadamente 25 rpm no veio de mistura.In general, said electric motor has a speed of approximately 1400 rpm which corresponds to a reduced speed in the gear motor and a speed of approximately 25 rpm in the mixing shaft.
Durante a utilização prática dos referidos misturadores, é frequentemente necessário - de preferência numa base diária 2During the practical use of said mixers, it is often necessary - preferably on a daily basis 2
ΕΡ 2 146 796/PT e em qualquer dos casos antes da argamassa residual consolidar - limpar o tanque utilizado para misturar os materiais diferentes.ΕΡ 2 146 796 / PT and in any case before the residual mortar consolidate - clean the tank used to mix the different materials.
Mais precisamente, é necessário remover depósitos sólidos da mistura das superfícies internas do tanque (incluindo os veios de mistura e as suas pás); esta operação é normalmente realizada por um operador que pode ficar posicionado do lado de fora ou do lado de dentro do tanque para assegurar uma limpeza mais eficaz.More precisely, it is necessary to remove solid deposits from the mixture of the inner surfaces of the tank (including the mixing shafts and their blades); this operation is usually performed by an operator who can be positioned outside or inside the tank to ensure more effective cleaning.
Em particular, a operação de limpeza dos veios de mistura contidos no tanque é especialmente difícil.In particular, the cleaning operation of the mixing shafts contained in the tank is especially difficult.
Tendo em vista o facto de cada veio ter de ser limpo no lado externo e no ponto de intersecção das pás ao longo de todo o comprimento, é um procedimento normal neste caso accionar o veio em cursos angulares curtos (nuns poucos graus de cada vez), de modo a tornar a operação de limpeza mais fácil para o operador dentro do tanque.In view of the fact that each shaft must be cleaned on the outside and at the point of intersection of the blades over the entire length, it is a normal procedure in this case to drive the shaft in short angular strokes (in a few degrees at a time) , so as to make the cleaning operation easier for the operator inside the tank.
Deste modo, as secções de superfície do veio a ser limpo estão sempre viradas para cima, quer dizer, numa posição mais confortável para o operador.Thus, the surface sections of the shaft to be cleaned are always facing upwards, that is, in a more comfortable position for the operator.
Em particular, são impostos cursos angulares curtos a cada veio de mistura por meio de impulsos eléctricos curtos impostos no motor eléctrico utilizado na unidade motora.In particular, short angular strokes are imposed on each mixing shaft by means of short electrical pulses imposed on the electric motor used in the motor unit.
Um tal princípio de operação não é considerado como sendo totalmente satisfatório, especialmente devido aos riscos para o operador dentro do tanque quando o veio de mistura é sujeito aos cursos curtos acima mencionados.Such a principle of operation is not considered to be entirely satisfactory, especially because of the risks to the operator inside the tank when the mixing shaft is subjected to the above mentioned short strokes.
Um possível mau funcionamento do dispositivo ou negligência do operador encarregado de enviar os referidos impulsos curtos à unidade motora pode resultar na rotação descontrolada dos veios de mistura à velocidade de operação normal, com consequências letais para o operador encarregado da limpeza. 3 ΕΡ 2 146 796/ΡΤA possible malfunction of the device or negligence of the operator in charge of sending the said short pulses to the drive unit may result in the uncontrolled rotation of the mixing shafts at the normal operating speed, with lethal consequences for the operator in charge of the cleaning. 3 ΕΡ 2 146 796 / ΡΤ
Deve ser notado que os veios suportam de modo radial as pás de mistura pesadas que podem provocar ferimentos muito graves no caso de interferência com o corpo do operador à velocidade de rotação normal. A GB 2 089 597 descreve uma máquina para trabalhar materiais em estado plástico em conformidade com o preâmbulo da reivindicação 1, que compreende um motor principal e um motor auxiliar que continua o processo de trabalho na eventualidade de falha do motor principal. A DE 38 14 211 Cl descreve um mecanismo de accionamento para uma extrusora que compreende um motor trifásico e um accionamento auxiliar que permite velocidades baixas económicas, mas também velocidades extremamente elevadas com grande binário. A finalidade especifica do presente invento consiste em melhorar a segurança de um misturador de betão durante a operação de limpeza realizada pelo operador dentro do tanque. Esta finalidade é conseguida por um misturador em conformidade com as caracteristicas da reivindicação 1.It should be noted that the shafts radially support the heavy blades which can cause very serious injury in the event of interference with the operator's body at normal rotational speed. GB 2 089 597 discloses a machine for working plastics materials in accordance with the preamble of claim 1, which comprises a main motor and an auxiliary motor which continues the working process in the event of failure of the main motor. DE 38 14 211 Cl discloses a drive mechanism for an extruder comprising a three-phase motor and an auxiliary drive which allows for low economic speeds but also extremely high speeds with high torque. The specific purpose of the present invention is to improve the safety of a concrete mixer during the cleaning operation performed by the operator within the tank. This purpose is achieved by a mixer in accordance with the features of claim 1.
Para esse fim, o princípio lógico com base nos cursos para a frente intermitentes acima mencionados dos veios de mistura obtidos com "passos consecutivos" curtos das unidades motoras foi completamente abandonado.To this end, the logic principle based on the above-mentioned intermittent forward strokes of the mixing shafts obtained with " consecutive steps " motor units was completely abandoned.
Em alternativa, a unidade motora do veio de mistura foi associada a um pequeno motor de engrenagem que é utilizado para a operação normal do misturador, mas é utilizada de modo vantajoso durante a operação de limpeza interna do misturador.Alternatively, the drive shaft of the mixing shaft has been associated with a small gear motor which is used for the normal operation of the mixer but is advantageously used during the internal cleaning operation of the mixer.
Num caso destes, o pequeno motor de engrenagem é utilizado para colocar em rotação, com a interposição da unidade motora tradicional, o veio de mistura correspondente a uma velocidade de rotação muito baixa (1 rpm).In such a case, the small gear motor is used to rotate the corresponding mixing shaft at a very low rotational speed (1 rpm) with the interposition of the conventional motor unit.
Parece evidente que a rotação lenta do veio de mistura não é perigosa para o operador de limpeza dentro do tanque. 4 ΕΡ 2 146 796/ΡΤIt seems evident that slow rotation of the mixing shaft is not dangerous to the cleaning operator inside the tank. 4 ΕΡ 2 146 796 / ΡΤ
Na realidade, ο operador poderá evitar as pás radiais pesadas que rodam muito lentamente dentro do tanque de mistura.In reality, the operator can avoid heavy radial blades that rotate very slowly into the mixing tank.
Com o fim da clarificação da descrição do presente invento, continuar-se-á a fazer referência ao desenho anexo, que se pretende que seja apenas para fins de ilustração e não num sentido de limitação, pelo que a Fig. 1 é uma vista lateral do misturador do invento.In order to clarify the description of the present invention, reference will continue to be made to the accompanying drawing, which is intended to be for illustration purposes only and not in a limiting sense, whereby Fig. 1 is a side view of the mixer of the invention.
Com referência à referida figura, o misturador (1) é tradicionalmente composto por um tanque paralelepipédico (2) proporcionado com um ou mais veios de rotação (3) suportados de modo horizontal entre os bordos transversais, de modo a misturar a mistura contida no tanque (2).Referring to said figure, the mixer (1) is traditionally composed of a parallelepipedic tank (2) provided with one or more rotating shafts (3) horizontally supported between the transverse edges, so as to mix the mixture contained in the tank (2).
Cada veio (3) é actuado por uma unidade motora correspondente (UM) composta por um motor eléctrico (4) ligado por meio de uma correia (5) a um motor de engrenagem (6) ligado ao veio de mistura correspondente (3) por meio de uma cascata de engrenagens intermédia e de redução. 0 motor (4) é consideravelmente potente pois, com a interposição do motor de engrenagem (6) e da cascata de engrenagens, acciona o veio de mistura correspondente (3) a uma velocidade que é suficientemente elevada para assegurar a mistura perfeita da mistura pesada densa contida no tanque (2) .Each shaft (3) is actuated by a corresponding motor unit (UM) composed of an electric motor (4) connected by a belt (5) to a gear motor (6) connected to the corresponding mixing shaft (3) by middle of a cascade of intermediate and reduction gears. The motor (4) is considerably powerful because, by interposing the gear motor (6) and the gear cascade, it drives the corresponding mixing shaft (3) at a speed which is high enough to ensure perfect mixing of the heavy (2).
Dentro da referida configuração tradicional, é aplicada uma roda livre (7) ao veio do motor eléctrico principal (4), e montada numa tal posição que não participa na rotação normal do motor eléctrico (4). A roda livre (7) está ligada por meio de uma correia (8) a uma polia (9) estriada para ligar ao veio de um motor eléctrico com baixa potência (10), de preferência 1 CV, que está montado numa posição adjacente ao motor eléctrico principal (4), sendo capaz de actuar o mesmo. 5Within said traditional configuration, a free wheel (7) is applied to the main electric motor shaft (4), and mounted in such a position that it does not participate in the normal rotation of the electric motor (4). The free wheel 7 is connected by means of a belt 8 to a pulley 9 which is grooved to connect to the shaft of a low-power electric motor 10, preferably 1 CV, which is mounted in a position adjacent the the main electric motor (4), being able to act the same. 5
ΕΡ 2 146 796/PTΕΡ 2 146 796 / EN
Antes da operação de limpeza, o motor principal (4) é desligado e o motor auxiliar com baixa potência (10) é alimentado.Prior to the cleaning operation, the main motor (4) is switched off and the auxiliary motor with low power (10) is supplied.
Devido à interposição da correia de transmissão (9), a actuação do motor auxiliar (10) provoca a rotação da roda livre (7) e consequentemente do motor principal (4) no qual a roda livre (7) está estriada. A rotação imposta ao veio do motor principal (4) está projectada para accionar no mesmo sentido de rotação toda a cadeia cinemática composta pelo motor de engrenagem (6), a cascata de engrenagens intermédia e de redução e o veio de mistura (3).Due to the interposition of the drive belt 9, the actuation of the auxiliary motor 10 causes rotation of the free wheel 7 and consequently of the main motor 4 in which the free wheel 7 is grooved. The rotation imposed on the main motor shaft 4 is designed to drive in the same direction of rotation the entire kinematic chain composed of the gear motor 6, the intermediate and reduction gear cascade and the mixing shaft 3.
Tendo em vista o facto de a potência do motor auxiliar (10) estar bastante limitada e a unidade motora (UM) ligada ao mesmo assegurar a redução da velocidade de rotação do veio do mesmo motor auxiliar (10), parece evidente que o veio de mistura (3) faça cursos de rotação extremamente lentos, os quais são praticamente imperceptiveis, permitindo assim que o operador no tanque interfira com total segurança e máxima eficiência na superfície do tanque e remova os depósitos sólidos.In view of the fact that the power of the auxiliary motor (10) is very limited and the motor unit (UM) attached thereto ensures the reduction of the speed of rotation of the same auxiliary motor shaft (10), it seems evident that the shaft of (3) makes extremely slow rotating strokes, which are practically imperceptible, thus allowing the operator in the tank to interfere with complete safety and maximum efficiency on the surface of the tank and remove the solid deposits.
De preferência, a velocidade de rotação do motor auxiliar (10) é 60-70 rpm, a qual corresponde a uma velocidade de rotação de 1 rpm no veio de rotação (3).Preferably, the rotation speed of the auxiliary motor 10 is 60-70 rpm, which corresponds to a rotation speed of 1 rpm on the rotation shaft 3.
Finalmente, deve ser notado que, sem deixar o âmbito desta ideia do invento, pode ser proporcionado um modo de realização diferente da ligação "selectiva" entre o motor auxiliar (10) e o motor principal (4) da unidade motora (UM).Finally, it should be noted that, without leaving the scope of this idea of the invention, a different embodiment of the " selective " between the auxiliary motor (10) and the main motor (4) of the motor unit (UM).
Apenas para fins de ilustração e não para fins de limitação, pode ser proporcionada uma embraiagem entre os veios dos motores principal (4) e auxiliar (10), sendo evidente, neste caso, que os dois motores podem ter o mesmo sentido de rotação. 6 ΕΡ 2 146 796/ΡΤFor illustration purposes only, and not for purposes of limitation, a clutch between the main (4) and auxiliary (10) engine shafts may be provided, it being evident in this case that the two motors may have the same direction of rotation. 6 ΕΡ 2 146 796 / ΡΤ
No caso de misturadores proporcionados com um único veio de mistura e uma única unidade motora, encontra-se associado um único motor auxiliar (10) à unidade motora.In the case of mixers provided with a single mixing shaft and a single drive unit, a single auxiliary motor (10) is associated with the drive unit.
Contudo, a utilização de um único motor auxiliar também é proporcionada no caso de misturadores com dois ou mais veios de mistura, uma vez que, num caso desses, os veios de mistura são acoplados por meio de uniões de velocidade constante.However, the use of a single auxiliary motor is also provided in the case of mixers having two or more mixing shafts, since in such a case the mixing shafts are coupled by means of constant speed unions.
Devido a isto, muito embora o motor auxiliar (10) coloque a rodar apenas a unidade motora especifica associada ao mesmo, a rotação do veio de mistura directamente actuado pelo último envolve a rotação simultânea (por meio da ligação proporcionada pela unidade de velocidade constante) do veio ou veios de mistura adjacentes.Due to this, although the auxiliary motor (10) rotates only the specific motor unit associated therewith, rotation of the mixing shaft directly actuated by the latter involves simultaneous rotation (by means of the connection provided by the constant speed unit) of the shaft or adjacent mixing shafts.
